Online banking blocked they say it is because of our security checker?

[AdaptableAnn]

My American bank has blocked me from logging in which I urgently need because they say one of my

internet security software plans is stopping it .  Also I have to clear something asking me to choose options for detected malware and it won't let me - won't let me delete it without going into task manager.

 

I am a silver surfer and would need very, very simple instructions to help me.  Please can someone 

advise I am desperate !
